WOODWORKING- MACHINERY.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Original application filed January 22, 1910, Serial No. 539,586. Divided and this application led August 5, 1910. Serial No. 575,740.

To all whom it may concern:

Be it known that I, LEWIS F. PARKS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Voodworking Machinery, (Case A,) of which the following is a specification.

My invention relates to that class of woodworking machinery employing a rotary cutter-head having a table at the front and a table at the rear of said rotary cutter-head and so arranged that stock is adapted to pass over the first of said tables to the cutter-head and in passing the cutter-head to be cut thereby, and particularly to so-called hand planers, in which the stock is passed over the tables and cutter-head by hand.

It is the object of my invention to provide novel means for adjusting and securing the tables; to provide a plurality of tables in front of the rotary cutter-head and to provide means for adjusting said front tables to relative elevations so that different elevations may be provided for said respective front tables, and to provide a table to rear of said cutter-head which is common to said plurality of front tables irrespective' of the relative elevations of the latter; and further, to provide a tilting gage common to all of said tables; and the invention will be further readily understood from the fol,- lowing description and claims, and from the drawings, in which latter:

Figure 1 is a plan view of my improved device. Fig. 2 is a side elevation ofthe same, partly broken away. Fig. 3 is a front View of my improved device showing the front tables at different elevations. Fig. 4 is a vertical section of the same on the line @-2 of Fig. 1. Fig. 5 is a cross-section of the same on the line g/g/ of Fig 4; and, Fig. 6 is a detail in Vertical section taken on the line -m of Fig. 4.

The present application is a division of my application for patent 011 combination wood-Working machines, filed January 22, 1910, Serial No. 539,586, to which reference is hereby made.

1 represents the main frame of the machine which may be of suitable construction.

2 is a main table, t-he framework of which is shown constructed of angle-irons and as comprising side angle-irons 3 connected by longitudinal angle-irons 4 secured thereto by bolts 5. y

6 is a mandrel journaled in bearings 7 on the main frame and has a cutter-head 8 scoured thereto. A pulley 9 or other suitable driving device is secured to said mandrel, the pulley being arranged to be driven from a counter-shaft suitably disposed, as to the rear of the main frame.

The main table further comprises inverted channel-irons 10 which extend at right angles to the mandrel and are secured to the longitudinal angle-irons 4 of the framework of the table by bolts 11. The side angle-irons of the table preferably extend rearwardly beyond the rear longitudinal anglciron and form'rear extensions 12 which are pivoted to upwardly extending portions 13 of the main frame as on pins 14. The main table is provided at its forward end with depending bars 15 having slots 16 through which clamp-bolts 17 are received into tie main frame, by means of which the main table is clamped in adjusted positions at various elevations. An adjustable table-plate 2l is located at the rear of the cutter-head, constituting a rear table for the machine, and a plurality of table-plates 22 23 are located side by side at the front of said cutter-head and rear table, constituting a plurality of front tables to which said rear table is common. Said front table-plates selectively or collectively act in conjunction with said rear table-plate. Means are provided for selectively adjusting said plurality of front table-plates to elevations with relation to each other and with relation to said cutter-head and common rear tableplate. By this means a Vroughing and a finishing cut may be taken oitl the stock without intermediate adjustment of tables, or greater depth of cut may be obtained at one side of the stock which is for instance of irregular shape in cross-section, and other operations performed without readjustment of parts.

For adjusting the table-plates, as shown, I provide inclined guides 24 formed within the bodies of said table-plates by undercutting, forming a cheap construction. The inclined guides or faces are arranged to rest on set-screws 25 adjustable in apertures 26 in the horizontal angles or Wings of the longitudinal angle-irons of the trame-work oi the table, clamp-nuts 27 holding the sety face of the rear table 21.

screws in adjusted positions. Each of the table-plates has a depending lug 28 in which a hand-screw 29 is journaled against endwise movement, said hand-screws being adjusted in threaded apertures 30 in the vertical wings of the front and rear longitudinal angle-irons of the framework of the main table. The set-screws 25 adjust the table-plates to the desired level and elevation and the hand-screws 29 adjust the same to elevation and toward and from the cutter-head. The construction provides means whereby the t-able-plates may be selectively placed at relatively desired elevations and also selectively adjusted toward and from the vertical plane in which the longitudinal axis of the cutter-head is located for selectively adjusting the distances of the respective tables with relation to each other and to said cutter-head, the tables being so located that the rear table is arranged to receive the cut face of the stock from either or both of the plurality of front tables, irrespective of their selective elevations, and providing means by which a roughing cut and a finishing cut may be imparted by one handling of the stock. Thus the table 22 may be set with its upper surface below the level of the upper surface of the table 23, the upper surfaces of both these front tables being set below the level of the upper sur- A roughingcut may be taken off stock by iirst passing it over the lower front table, the cutter-head and rear table, and the same piece of stock may then immediately be passed over the higher front table, the cutter-head and rear table for imparting the finishing cut to it. Or stock may be thicker at one edge than at the other and it be desired to reduce the same to even thickness, which can be done by properly adjusting the relative elevations of the front tables. Other operations can also be performed by my improved device.

Each of the table-plates is clamped in adj usted positions by a clamp-screw 31 received in a threaded aperture 32 in the table-plate and surrounded by a tube 33 having end abut-ment against a hand-wheel 34 of'the clamp-screw and a cross-bar 35 received shiftably against the lower faces of one of the side angle-irons and of the inverted channel-irons of the main table. The construction stated also permits said rear tableplate 21 and said front table-plates ,22 23, which latter are located side by side, to be adjusted to coincident level with or to elevations with relation to the upper surface of the inverted channel-irons 10 for forming a rigid upper stock-supporting surface and forming a combined table, which may be combinedly adjusted to elevation with relation to the cutter-head by being adjusted upon its pivots 14 and clamped in adjusted position by the clamp-bolts 17.

For limiting the downward movement of the main table, set-screws 36 are threaded into the main frame and held in place by j ani-nuts 37, the lower end of one of the vertical wings of one of the forward longitudinal angle-irons of the framework of the main tablebeing arranged to rest upon the set-screws when the table is in normal or level position. This construction further permits the front end of the main table to be brought to an elevation lower than the rear, end of the main table if it is desired to give the table-plates a collective rearwardly ing a slot 49 through which a clamp-screw Thus the side- 50 passes into threaded connection with the slide. There is one of these pairs of links 45 46 and clamp-screws 50 at each end of the slide. By these means angular adjustment is given to the gage-plate. Lateral adjustment may also be imparted to the sidegage. Thus 51 are brackets secured to the horizontal wing of the right-side angle-iron of the framework of the main table by bolts 52 and are located at the side of the front table-plates, the gage-plate 42 extending rearwardly above the front and rear tablej plates and the cutter-head.

53 is a supporting plate adjustable laterally on the brackets by providing the brackets with a series of apertures 54, bolts 55 being received through said apertures 54 and apertures in said supporting plate, handnuts 56 received over said bolts clamping the supporting plate in adjusted positions on the brackets. The slide 48 is provided with'a laterally extending bar 57 adjustably secured in a clamp 58.

The clamp 58 comprises an upper clamppiece 59 loosely spaced from the lower plate by a bolt 60 at one side of the bar 57, there being a clamp-screw 61 which passes through the said clamp-piece at the other side of the bar 57 and is threadedl into the lower plate for clamping the bar between the lower plate and upper clamp-piece. By this means, the bar may be adjusted lengthwise in the clamp for adjusting the side-gage laterally, and the clamp may be adjusted laterally on the brackets for increasing the range of adjustment of the side-gage, and the gage-plate be adjusted to positions above any of the tables.

Having thus fully described my invention,
